This part of IEC 61000 specifies immunity requirements for electrical and electronic equipment when it is exposed to radiated electromagnetic energy from RF transmitters used in close proximity. It establishes test levels and the required test procedures. The applicable frequency range is 9 kHz to 6 GHz. Fixed-installation equipment being exposed to portable transmitting devices, mobile equipment exposed to fixed transmitting devices and mobile equipment exposed to other mobile transmitting devices are considered.
The object of this document is to establish a common reference for evaluating the immunity requirements of electrical and electronic equipment that is exposed to radiated, RF electromagnetic fields from sources at close distances. It is understood that this part of IEC 61000 does not replace general immunity requirements of electrical and electronic equipment to radiated electromagnetic energy as given in IEC 61000-4-3 and other parts of IEC 61000 and that it is only applicable if an equipment or system is exposed to disturbance sources in close proximity.
In the context of this document, "close proximity" generally refers to a separation distance between the source and victim equipment of less than or equal to 200 mm for frequencies greater than 26 MHz and 500 mm for frequencies lower than 26 MHz.
The test methods documented in this part of IEC 61000 describe consistent methods to assess the immunity of an equipment or system against a defined phenomenon in the respective frequency range. Product committees would consider the applicability of the test and then if necessary select the applicable test method depending on the EUT, frequency range, disturbance source, etc.
NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products.
This document deals with immunity tests related to RF magnetic and electromagnetic fields from any source used in close proximity to other electrical or electronic equipment or systems.
This document is an independent test method. Other test methods should not be used as substitutes for claiming compliance with this document.
